Winter Tires
The initial movement and acceleration of any vehicle in winter or other adverse driving conditions are dependent on the traction available from the tires on the driving axle. However, the handling, cornering and braking of a vehicle after it is in motion, especially in any adverse weather conditions, are dependent on the traction from both the front and rear tires. The rear tires of any vehicle must have comparable or higher traction capabilities than the front tires in order to optimize vehicle mobility and control, especially during sudden maneuvers.
Winter/Snow tires - It is always preferable to apply winter/snow tires to all wheel positions, including duals, to maintain vehicle mobility and control.
If winter/snow tires are applied to the front axle of any vehicle, winter/snow tires must also be installed on the rear axle. DO NOT apply winter/snow tires only to the front axle. This applies to all passenger and light truck vehicles including front-wheel-drive, 4WD, and AWD vehicles. WARNING! Without winter/snow tires on the rear axle, which have comparable traction qualities to the tires on the front axle, the vehicle may experience adverse handling characteristics. This may result in loss of vehicle control, which could cause serious injury or death.
If winter/snow tires are installed on the rear axle of any vehicle, it is recommended that they also be installed on the front axle.
Studded Winter/Snow tires - Studded winter/snow tires have higher traction qualities under most winter weather conditions.
If studded winter/snow tires are installed on the front axle of any vehicle, studded winter/snow tires must also be installed on the rear axle. DO NOT apply studded winter/snow tires only to the front axle. WARNING! Installing only two studded winter/snow tires on the front axle of any vehicle (including front-wheel-drive vehicles) without studded winter/snow tires on the rear axle can cause adverse vehicle handling characteristics. This may result in loss of vehicle control, which could cause serious injury or death.
If studded winter/snow tires are installed on the rear axle of any vehicle, it is strongly recommended that they should also be installed on the front axle. Only if studded winter/snow tires are installed on all wheel positions of a vehicle will optimum handling characteristics be achieved.
С две думи, слагат се 4 зимни гуми за да може колата не само да тръгва в снега, но когато започнеш да спираш да имаш същият спирачен ефект на предна и задна ос.
Още едно обяснение, което включва че ако все пак си решил да сложиш само 2, то трябва да са на задният мост, без значение кои са задвижващите колела, защото това което се гледа е как спираш, а не как ускоряваш в снега. Не съм го измислил аз, написали са го хора които са правили излседване по въпроса.
NEVER put only 2 snow tires on the front, and it doesn't matter if you have FWD, RWD, or AWD. Your front will stop faster than the rear, and throw you into an uncontrollable spin. If you are too cheap to buy 4 snows, put the 2 on the rear, for safety. It doesn't matter how well you can accelerate, what counts is stopping. No reputable shop will put 2 snows on the front.
Buy 4 for the best combination of handling, safety, etc.
и няма да занимаваш чичковците по паркингите.
Аз поне така правя. Защото повечето ми познати дето миналата зима сложиха зимни гуми, а нямаще и 1 мм сняг и беше доста мека и топла зимата..накрая се оплакваха , че гумите им са заминали и не стават за нищо. Бяха добри маркови доколкото си спомням
